How do you know if a vacuum has strong suction?

Determining if a vacuum cleaner has strong suction involves a few key factors and tests you can perform:

  1. Manufacturer’s Specifications: Verify the vacuum’s specs for suction power, which is often expressed in watts (W) or air watts (AW). Stronger suction is usually indicated by higher numbers.
  2. Surface Performance: Test the vacuum on different surfaces (carpet, hardwood, etc.). A vacuum with strong suction should effectively pick up debris and dirt from various surfaces.
  3. Airflow and Wattage: Examine the wattage and airflow, which are expressed in cubic feet per minute, or CFM. Higher airflow and power indicate greater suction; however, efficiency is also influenced by the vacuum’s design.
  4. Sound and Feel: Listen to the sound of the vacuum. A deeper, more robust sound can sometimes indicate strong suction. Also, feel the suction at the hose or nozzle.
  5. Pick-Up Test: Try picking up different types of debris like pet hair, dust, and larger particles. A strong vacuum should handle a variety of debris sizes effectively.
  6. Filter Check: Ensure the filters are clean. Clogged filters can significantly reduce suction power.
  7. Bag/Canister Check: A full bag or canister can also reduce suction. Check if performance improves after emptying it.
  8. Hose and Attachments Check: Inspect for blockages or damage in the hose and attachments, as these can also affect suction.

Remember, strong suction is important, but it’s not the only factor in a vacuum’s effectiveness. Other aspects like filtration, maneuverability, and ease of use also play significant roles in overall performance.
